He began teaching at his alma mater in 1876 and would become a professor in 1891. Orest Khvolson authored a number of works on electricity, magnetism, photometry, and actinometry. He proposed the designs of actinometer and pyrheliometer, which would be used by the Russian weather stations for a long time. After 1896, Khvolson was mainly engaged in compiling the five-volume Physics Course ( ), which would improve immensely the teaching of physics throughout the country and remain a principal textbook in universities for years to come. It was even translated into the German, French, and Spanish languages."}
